Only famous artists! Anime songs that energize the Reiwa era
When it comes to anime songs, in the Showa era there were many child-oriented tracks made specifically for each anime, while in the Heisei era there were many tie-in songs that often had little to do with the anime’s storyline.
In contrast, these days there are more and more songs written for anime that have also become signature hits for the artists themselves.
This may well be because Japanese anime has gained popularity overseas.
So this time, we’ll be introducing songs that serve as theme songs for some of Japan’s most iconic anime works!
